ACETYLEN-E-GAS BURNER.

SPECIFICATION forming part of Letters Patent No. 683,262, dated September 24, 1901,

Application filed April 15, 1901.

I citizen of theUnited States,residin g in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Acetylene Gas Burners,0f which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of gasburners used in the consumption of acetylene gas for illuminating purposes, the object of the invention being to provide a burner Wherein provision is made for the complete intermingling of air in the mixingchamber with the gas, and wherein the mixed gas and air are caused to be delivered from the mixingchamber in a more effectual manner than in burners of the same class as at present constructed.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a perspective View of a burner constructed accordingvto my invention. Fig. II is an enlarged longitudinal sectional view of one of the burner-tips. Fig. III is a crosssect-ional view taken on the line III III, Fig. II. Figs. IV, V, and VI are cross-sectional views similar to Fig. III, illustrating modifications.

1 designates the body of the burner, which maybe of any desirable form or configuration.

2 designates the burner tips, containing mixing-chambers 3 and having necks 4, provided with gas passage-ways 5. (See Fig. II.)

In the burner-tips 2 are air-ducts 6, that extend from the outer surfaces of the tips inwardly to the mixing-chambers 3 and enter said mixing chambers tangentially to the wall of said mixing-chambers, as most clearly shown in Fig. III. The air-ducts 6, in addition to entering the mixing chambers 3 at a tangent to the walls thereof, are also preferably positioned at an angle relative to the wall of the mixing-chambers, as seen in Fig. II, so that the air passing therethrough from the exterior of the tip into the mixing-chain ber enters said chamber at an angle to the Wall thereof and in a .direction toward the Soria1No.55,893. (No model.)

mouth of said chamber. The air-ducts 6 may be of any desirable number and may extend to the mixing-chamber from the corners of the burner-tips, or from points intermediate of the corners of the tips.

In the form of burner shownin Figs. 1, II, and III the ducts are four in number and extend from the corners of the tips.

In the modification shown in Fig. IV the In the practical use of the burner the gas enters the mixing-chamber 3 from the passage way 5, and the pressure 'under which it flows causes air to be drawn by suction through the ducts 6 into the mixing-chamber to mingle with the gas. As the air is drawn into the mixing-chamber through the ducts, tangentially arranged, as explained, the said air circulates in the mixing-chamber in a rotative or whirling motion as a result of the tangential introduction. As a consequence a whirling or rotative motion of the intermingling gas and air is produced, so that the gas and air are thoroughly combined before delivery from the mouth of the mixing-chamber for consumption. The entrance of the air through the ducts in an inclined direction relative to the wall of the mixing-chamber causes the gas and air to be directed toward the mouth of the mixing-chamber, with the result that the mingled gas and air receive the impulse of the inrushing air and are caused to flow from the chamber as rapidly as the proper mixture is obtained.
